C#实现网页表单自动提交(126邮箱登录例程)

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)

{

#region 参数设置

HtmlElement btnSubmit = webBrowser1.Document.All["enter.x"]; //获取登录对应元素

HtmlElement tbUserid = webBrowser1.Document.All["user"]; //获取用户名对应元素

HtmlElement tbStyle = webBrowser1.Document.All["style"]; //获取版本对应元素

HtmlElement tbPasswd = webBrowser1.Document.All["password"]; //获取密码对应元素

if (tbUserid == null || tbPasswd == null )

return;

tbUserid.SetAttribute("value", txtUseName.Text); //给用户名赋值

tbPasswd.SetAttribute("value", txtPassWord.Text); //给密码赋值

tbStyle.Children[Convert.ToInt32(txtstyle.Text)].SetAttribute("selected", "selected");//设置版本

btnSubmit.InvokeMember("click"); //模拟点击登录按钮

#endregion

}

在确定按钮的响应函数btnOK_Click中添加如下代码：

private void btnOK_Click(object sender, EventArgs e)

{

webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);

webBrowser1.Navigate("http://www.126.com");

}
